Earlier this week, I was being briefed by HP about some recently released workstations. As we were moving through the slide-deck, a small item caught my attention: one workstation claimed to have 2 USB ports on the front panel, 6 on the back, and 2 marked "internal." Why, I asked, would anyone want an internal USB port on a PC? Care to guess?
The answer is: for dongle keys. Yeah, they're still around and they use USB form factors. The internal aspect is interesting. It's designed so you can insert the dongle, lock the PC and nobody walks off with the dongle key.
I honestly would never have guessed.
